Update for those hoping for Linux support: here's a preview of Reconnaissance running on Linux Mint (x64) and Ubuntu (arm64).

You'll need both a USB to Serial (DB-9) adapter and a cable to go from DB-9 to Mini-DIN-8 serial. To connect the USB adapter to your computer you'll probably also need a USB A to C cable or adapter unless you have USB-A ports. See attached photo. Pictured: OIKWAN USB to RS232 Adapter with FTDI...

Sounds like we had the same idea! The Universal ROM sources are helpful but some of the details of how the test commands vary on different machines are kind of hard to decipher from that with all the conditionals and codenames for stuff. So to get a better understanding and figure out some...

I think this is the M0199 Mac Plus peripheral adapter I mentioned in my original post. I don't have one to try (yet). Are you able to try it, or to check it with a multimeter to see if the correct pins are connected? I put a pinout reference here. There are only 3 pins + the shell that need to...

Absolutely, I would love to see what you've figured out and hopefully incorporate it. I'll be sharing my source code soon too.

My plan is that the next update will lower the minimum requirement to macOS 12 (Monterey).

Thank you thank you! I intend to support all systems that the TechStep supports, and I would also like to support later machines that have a diagnostic monitor built into the ROM that's accessible by serial connection. I haven't made a full list of what falls into what category, but this is...

My primary #MARCHintosh project for this year is a brand new diagnostics app that runs on modern machines and makes it easy to access the diagnostics mode built in the ROM of many Classic Macs. If you're struggling to get a Sad Mac working, I hope this project can help! Official announcement...

Creating this thread to track USB-Serial adapters and cables that can be used to make a serial connection between a Classic Mac and a modern machine. In case you haven't seen it: Reconnaissance: Modern Diagnostics for Your Classic Mac USB Serial Adapters Mac hosts: adapters with the FTDI...

#MARCHintosh 2026 is here and I'm excited to share a project I've been working on. https://reconnaissanceapp.com You may know that many Classic Mac models have a diagnostics mode built into the ROM that you can access over a serial connection. But it's extremely cumbersome, limited, and there...

Ditto having to disable the SNMP extensions or I was getting a crash on startup on 7.5.5 (on a IIfx i.e. 68030). These are the extensions to disable: Also, @slomacuser are you using Open Transport networking? Apple Internet Router is not compatible. If you installed it, it's possible to...

Indeed I am on MacTCP 2.0.6 (System 7.5.5). There isn't any readable text over to the right, but there are a few normal-looking entries in the log too, as seen here.

Thanks, I have a digital vernier calipers so I'll give it a go and see what happens. Fortunately, the 600e bezel isn't curved across the front so that should simplify things a bit.

These are awesome! I printed the CD-ROM bezel for my G3 Tower and it looks great! What is your process for initially creating a 3D model for these? Do you start with a 3D scan? The bezel on the front of the AppleCD 600e enclosure is made out of the plastic that turns to dust when you look at it...

Is anyone else seeing gobbledygook in their Apple Internet Router Log? I see the same message repeated over and over again so I'm thinking something is pointing to an incorrect memory location rather than it being something like a character encoding issue. Seeing this kind of thing always makes...
